There's a third bullet point, and in that bullet point the word "gay" isn't italicized and no one goes "haha."

It's just a statement of fact, because, even though as you note we probably have some confirmation bias about ultra rightwing anti gay people "ending up being gay," it certainly certainly certainly seems to be a thing.

And pointing it out isn't homophobic or stereotyping. There's some scary, sad, self-hating shit that goes on in fascist hearts and minds, and it's not some labyrinthine psychological leap to get from closeted, virulent anti-gay politician to bukkake.
